INCINERATOR.

Applicati'en led November 13, 1923. Serial No. 674,535.

To all whom 'it may concern:

Be it known that I, IVILLIAM G. ARRO- wooo, a citizen of the'UnitedStates, residin at Hawthorne, in the county of Los Ange es and State ofCalifornia, have invented new and useful Improvements in Incinerators,of which the following is a specilication.

The present invention relates to improvements 1n mclnerators,

and particularly to p apparatus of this character which is intendedprimarily for safely burning garden or lawn trash or rubbish orhousehold waste materials. I

An object of the invention is to provide a durable device or apparatusfor the purpose described, which s all be relatively inexpensive ofmanufacture whose parts may, if1 gesired, be readily separated or assembe With this and other objects in view, the invention resides in theconstruction and ar rangement of parts that will be hereinafter moreparticularly described and pointed out in connection with theaccompanying draw-I lIt will be understood that in the drawing some ofthe parts are shown more or less conventionally, and that unless secifically included in the ap ended claims, t e invention is notintended to be limited to the exact details illustrated, the drawino'being designed to be illustrative rather t an restrictive of theinvention.

In the drawing i Figure 1 is an elevation of an incinerator constructedin accordance with the present invention.

Figure 2 is a vertical section substantially dn the line2-2 of Figure 1.

Figure 3 is a horizontal section substantially on the line 3.-3 .ofFigure 1.

Figure 4 is a detail perspective view of a portion of one of the cornerpieces 'or up rights and of two of the metal elements of the incineratorwalls. y

Referring to the drawing, it will be seen that the embodiment'of theinvention illustrated is composedfof four uprights or corner pieces 1,walls connecting said corner pieces and formed of a plurahty of coursesof brick or tile' 2 separated by metal'bars', and a top 4, whichembraces the upper ends of the walls and corner pieces or posts.

of the side walls,

The metal corner Ipieces or uprights 1 are of such form in them willembrace the adjacent ends of two and, as above stated, all of saidcorner pieces and the walls are held together by the top or cap piece 4.

To insure stability of the apparatus, spur pieces or anchors 5 may beprovided, which will be embedded in the ground with their upper endsextending into the lower ends of the uprights or posts 1.

AS. shown, each corner piece or. upright is formed from a sheet metalblank, which is folded uponl itself to provide two longitudinal channels6, 7, arranged at right angles to each other and the ends of the sidewalls extend into these channels.

Each side wall is preferably composed of a plurality of courses of brickor tile, the term brick being hereinafter employed as descri tive ofblocks, slabs or lates of any suita le ireproof material. T e brickscross section that each of site faces of one of the courses separated bythe bars.

In the particular embodiment illustrated,

the separating bars 3 are arranged with their channel faces upward, sothat the lowerf edges of the bricks 2 are fitted snugly therein.

Referring to the drawings it will be seen that the lower tier of brickinclude members 11 extending parallel to opposite sides of theincinerator body and forming passages 10, which extend throughout thewidth of the apparatus and are open at both ends. The passages 10 thusformed provide a ready means for removal of ashes and the upper edges ofthe walls 11 of such passages serve as supports for the materialbeingburned.

The outer side walls of the supported:y as shown, rating bars 3.

In one of the side walls, the bricks are so arranged as to leave an oening 12, through which the contents of tlie apparatus may be ignited.

The top 4 is preferably made of metal, and has a marginal Hat basesection resting on the top of the side walls and having dependingmarginal flanges 13, which closely embrace the sides of the walls andthe uprights 1. Said top is provided with a smoke outlet 14, about whichmay be fitted a suitable stack 15, and one wall of the top is inclinedfrom the outlet 14 forward to the portion 16 which rests upon the upperends of the walls. In this inclined section of the top is formed anv,opening which is closed by a door or cover 17 pivotally mounted orhinged to a suitable frame as at 18. As

shown the opening in the top is provided at opposite sides withoutwardly projecting members 2O and the cover 17 has an outwardlyprojecting marginal flange 21. The pivot rod 18 extends lthrough theframe members 20 and adjacent sections of the marginal door flange 21.The lower, transversely extendingbs'ection of the door flange is adaptedto extend parallel to the section 16 of the top 4 when the door is inopen v A screen 19 is preferably placed across the smoke outlet 14 toprevent flaming particles from being carried out of the apparatus whenin use.

It is believed that the operation and adf vantages of the apparatus willbe evident from the foregoing description taken in connection with thedrawing. The apparatus may, of course, be made in various sizes and ofdiiferent forms. YThe parte thereof can be readily assembled in positionfor use, or, if desired, can be disconnected and stored ina minimumamount of space. The corner pieces and bars/separating the brick of theside walls may be of relat1vel'yl lightV metal and when `the parts areassembled, a strong and durable apparatus is' provided.

' The side walls and corner pieces4 are lsecurely interlocked whenassembled,` and there is no danger of fire escaping to'dal'nage articlesoutside of the it is .in use. y f
